Application filed November 21, 19(16. Serial No. 344,456;

To all whom it my camera:

Be it known that l, FRANK L. Snows,

- citizen of the United States, and resident of 1 ful Improvements in Ty chines, of which the following is a specifica- Chicago, in the county of Cook and State of Illinois, have invented certain new and use pe Writing Ma tion. r My invention relates more especially to paper suplply devices for typewriting machines an has forflits main object to provide an improved roll holder and supports therefor. v

The invention is particularly well adapted to the 'Monarch fronbstrike typewriter and is shown applied to the carriage-of that machine but certain features of the invention may be embodied in other forms of writing machines and may be used on the framework or stationary art of such machines as well as on the carriage or movable parts thereof.

To the above and other ends the invention consists in the featuresof construction, combinations' of devices and arran ements of parts hereinafter fully described and particul'arly pointed out in the claims.

In the drawings, Figure 1 is a ifragmen v tary front elevation showing the upper part of a Monarch typewriter with the carriage thereon and my invention applied to said carriage, parts being sectioned and broken and parts being omitted for the sake Z of c earness. vliig. 2 is a side elevation 'of'the parts shown in Fig. 1. Fig. 3 1s a plan view ona reduced scale of a tag strip such as may beused in roll form in connection with my improved roll holder. Fig. 4e is an enlarged fragmentary view showing the connection between the left-hand supporting bracket of the roll holder and the platen carrier.

In the drawings, the top plate 1 oi the ma.

chine-has rising from it at the rear, stand- 'bars 7 ropecting horizontally forward from the on s of said rear bar. Jonrnaled in the side bars 7 1s a platen 8, operatively connected with the left-hand end whereof is a .55 eel-sweetened line space ratchet wheel 9.

Cooperative with the "teeth (if the ratchet wheeh 9 is a roller detent 10 journal'ed at the forward end of a spring arm 11, the rear end of said "spring arm being secured by a headed screw 12 to a' lug 13 projecting inwardly fromthe rear portion of the left-hand side bar 7 of the'platen frame 'or carrier. The detent 10 coiiperates with the ratchet wheel -9 to maintain it,'and through it the platen 8-,

in desired line 3 ace position, and said platen.

e turned from one 'line to another by the usual line spacing devicescomprising a awl 14 and a handle or lever is adapted to arm 15 by which said pawl is operated. A paper table 16 is'arranged at the rear of the platen; and receives and ides the work sheet into position to be ed around with said platen by the usual aper feeding devices, said paper feeding evices comprising feed rolls 17 and 18 which are diagrammatically indicated. As the work sheet is fed forwardly and upwardly from the forward feed roll 18, said work sheet is adapted to co operate with the usual pa er fingers '(not shown), said paper fingers eing adjustably mounted .on a supporting rod or bar 19 which bar is arranged longitudinally of the platen above the same andv slightly to the rear of its axis. The ends of the bar or rod 19 are supported in logs or e 'itensionsZO rising from the side bars 7 of the platen frame and said rod or bar is maintained in fixed relation with said platen frame 'by headed screws 21 which are supported in the ends of said rod.

Referring more especially to m attachments,.the' roll holder is mounte porting brackets 22 made preferably of sheet metal and bifurcated at their lower ends to form downwardly extending arms 23 and24.

in sup- The lower portion of the forward arm 24 of each bracket is providedwith a lateral inwardly extending. collar portion 25 which cooperates with the rod or bar I9, the latter passing through the collar portions of the brackets. The lower end portionof the rear arm 23 of the right-hand bracket 22 is formed with a threaded hole to receive a headed screw 26 which passes through an opening in the right-hand side bar 7 and engages with said threaded hole in the arm 23. The lowerend of the rear arm 23 of the left-hand bracket 22 is formed with a slot 27 which cooperates with the screw 12 to assist in hol ng the left-hand bracket 22 its in fixed relation with the platen frame. In securing the left-hand bracket arm in place on the laten frameit is only necessary to loosen t e screw 12 without entirel removing it and then to slip the slotte end of the arm 23 over the shank of said screw and-between the under side of its head and the spring arm 11. The rod 19 is, ofcourse, removed until; the two'brackets 22 and 23 are properly positioned after which said rod is replaced so as to pass through the collar portions 25. The rod .is then secured in place by'its screws 21 and the screws 12 and 26 ire screwed into engaging positions. It

will be noted that the only change necessary in the ordinary construction of the platen frame or carrier to enable the supporting brackets 22 to be mounted thereon IS the provision of the opening in the righthand side bar 7 through which the securing screw 26 passes. The brackets 22 extend almost straight upward from the platen frame and support the roll holder at their upper ends and this arrangement enables the said brackets to be made of comparatively light material and yet withstand the strains to. which they will be subjected.

,As shown in the front view the upiper ends of the brackets 22 are slightly 0 -set inwardly toward each other, and, as seen from the side, each of said brackets is formed at its upper end portion with a downwardly extending slot 28, the closed lower end of said slot serving as a bearing for the roll holder.

The roll holder comprises a tubular shaft 29, the ends of which are closed by blocks or plugs 30, said plugs being suitably secured in place, as by being sweated in. The plugs project'outwardly from the ends of the tubular shaft and the projecting parts are reduced indicated at 31, the reduced parts resting'in the slots 28 and serving as earings for the tubular-shaft 29. The outer end portions of the parts 31 are knurled as shown at 32 and afford convenient means for manually turning the shaft. A disk-like flange 33,- is mounted on each of the reduced bearing partsll, said flange being formed. with a central opening which receives a bushingj34t, the latter being driven into the opening in the flange or otherwise suitably secured therein. The bushings 3-1 have heads arrangedoutside the flanges 33 and each of said bushings is provided with a central bearing opening which cooperates with the bearings 31. The openings in the bushings are large enough to permit the flanges 33 .to be readily slipped on and off the bearings 31. Normally, as will be understood from a consideration of Fig. 1, the inner faces of the flanges 33 contact with the ends of the tubular shaft 29 and with the shoulder; formed by the junction of the blocks 30 with the. reduced bearing parts 31. The

parts are proportioned so that the distance the bushings is slightly less than the distances between the inner faces of the upper ends of the brackets 22 so that the assembled roll holder, comprising the tubular shaft and flanges 33, may be readily entered in or removed from the slots 28 at the upper ends of said brackets 22.

The roll holder receives a roll of paper or other material to be written on, and this material may, of course, be of any desired sort. I have illustrated in detail in Fig. 3 of the drawings a roll of ta s to which my invention is especially Well a( apted. Widthwise the tag roll comprises three tags 36 arranged end to end and adapted tobe sepaetween the outer faces'of the heads 35"'of rated along the dotted lines 37. Each tag is provided with a hole 38 near one end by which the tag, after being written, is

adapted to be hung on a hook in a car record apparatus in which this style of work sheet' is employed. The tags are that the rolloof tags when wound up and be fore being written and separated, comprises a practically continuous web or roll of material.- The holes 38 and the lines of separation 37 and '39 have been omitted for convenience from the showing in Fig. 1. The roll of tagsis wound upon wooden core sections 40 which are arranged end to end, one core section for each width of tags. Of course, it will be understood, that while I have illustrated a tag roll comprising three tags widthwise et, nevertheless, tag rolls only one. tag wid e may be employed, or tag rolls of any other width, the roll holder being made of a width corresponding with the tag roll employed. In arranging thetag roll in place, the roll holder is removed from the supporting brackets and one of the flanges 331s slipped off, after which the tubular shaft 29 is passed through the wooden core sections 40, the flange 33 is replacedtand-the roll holder carrying the roll is mounted in place on the supporting brackets 22. The free end of the tag roll is passed downwardly from behind said roll as shown in Fig. 2 and thence over the paper table and into the machine where it is written upon in the usual-way,

It will be seen that the roll holder is dis posed quite close to the platen and that the work sheet or web of tags is fed into the machine at a convenient angle. The tags are comparatively thick and the tag roll correspondingly weighty, and heretofore it has been customary to support rolls of this kind on a stationary part of the machine, and owing to the stiffness of the tag sheet and the relative endwise movement between the tag roll and the carriage as it is moved back and forth, some special arrangement or device has heretofore been employed to avoid the twisting of the tag sheet and the obstruction of carnage movement. By mounting the tag roll on the carriage itself, I am enabled to maintain the roll holder always in the same relation with the carriage, and, aside lnore, it will be seen that the roll is about centered over the guides 3 and 6 and the antifriction rollers 5 by which the carriage is supported in its tratvel'and that the weight t of the roll does not therefore materially affect the carriage in its travel. It will also be seen that the roll holder is in the nature of an attachment which may be readily attached to or detached from existing styles of typewriting machines without changing the structural features of such machines or the operation thereof.

Various changes may be made without departing from the spirit and scope of my invention.
